Summary: | Glomerella cingulata (Stonem.) Spauld. & Schrenk f. sp. phaseoli, better known in its anamorphic state Colletotrichum lindemuthianum (Sacc. & Magn.) Briosi & Cav., is a causal agent of anthracnose in beans (Phaseolus vulgaris L.). Ultrastructural aspects of the perithecial hyphae of this pathogen were studied. The perithecia hyphae septal pores were found either plugged by a vesicle or unplugged. Some perithecia hyphae septa presented no pore. The Woronin bodies, close to the septal pores, appeared as globose structures which were more electron dense than the occlusions plugging the septal pore.
Glomerella cingulata (Stonem.) Spauld. & Schrenk f. sp. phaseoli, conhecida no seu estado anamórfico como Colletotrichum lindemuthianum (Sacc. & Magn.) Briosi & Cav., é agente causal da antracnose do feijoeiro (Phaseolus vulgaris L.). Aspectos ultraestruturais das hifas do peritécio deste patógeno foram observados. Os poros dos septos das hifas do peritécio apresentaram-se obstruídos com uma vesícula ou livres. Alguns septos das hifas do peritécio foram observados sem poros. Os corpos de Woronin, próximos aos poros dos septos, mostraram-se como estruturas globosas mais eletrodensas que as obstruções encontradas nos poros. |
